Abstract

A spectrophotometry method was developed for the determination of diamino acids (ornithine and lysine) based on their reaction with [Fe (CN)5NO]2- to produce N-heterocyclic amino acids (proline and pipecolic acid). The cyclic amino acids were measured spectrophoto-metrically based on the well-known Simon-Awe method.
